Planiel Light Firsl PLF), a producer of cricgrcfficient lighl bulbs. cxxccls that command will increase markedly over the next decide. Duc lu the high fixed cusis involved in the business, PLF has decicx lo evalualc ils financial performance using absorption coeling income. The procclicn-cure var ance is written off to cost of goods sold. The variable cost of production is 82 so per bulbo Fixed manufacturing costs are S1 170.000 per year Variable and fixed selling ing and administrative expenses are Sa 25 per bulb sold and $270 000 respectively. Because its kint bulbs are currently popular with environmentally conscious customers. PLF can sell the bulbs for 59.50 each. PLF is deciding among various concepts of capacity for calculating the cost of each unit produced. Its choles are as follow (click the icon to view the capacity Information.) Road the recents Requirement 1. Calculate the inventoriable cost per unit using each level of capacity to compute fixed manufacturing cost per unit Beyin by determining the formula to calculate the inventorieblo cosi per unit.
